On Kinnikuman's world, there is a thing called Friendship Power (友情パワー, Yūjō Pawaa). And now that Suguru has started to make some genuine connections with people here, I thought I would explain what it is and how it might affect you.
Friendship Power is, as the name suggests, power created by friendship. More or less, it is the ability to defy logic and reality (called miracles for ease) through the connections that people share. The stronger the connection, the stronger the miracles that can be created. The power is never really explained in detail in the canon, so I'm just sorta extrapolating from what I've seen. Here are some of the things that Friendship Power has done throughout the Kinnikuman stories.
Omens
When someone is in trouble, reality conspires to let their friends know. Each person has a different method of receiving omens; Kinnikuman's occurs in the form of something reminding him of a friend, and then something relevant to the danger they're in occurring to that object. Terryman receives omens in the form of a shoe lace breaking and he simply knows through intuition who is in trouble. Warsman receives warnings in the form of birds acting strangely at one point. Naturally, this can work both ways-if Suguru cares about your character, and they care back, then they can get omens of each other. The feeling doesn't have to be that strong, but the omens are as obvious as the feeling is strong; so sometimes they'll not be noticed.
Wordless Communication
To Friendship Power, things like distance, physical condition and even life and death mean nothing when it comes to communication. It comes in a couple of forms: When Ramenman was brain dead, he was able to speak to Kinnikuman in a voice only he could hear. When Kinnikuman was sealed in another dimension, he could still hear the words of Terryman on the outside. Several times the spirits of the dead or those too severely injured to be there in person can still talk to Suguru. Generally, this is only happens when it's a matter of needing to communicate, not just when someone wants to. However, if someone thinks or feels something to do with their friend with an incredible conviction, they can almost always pick up on it. Thinking something like 'I really wish Suguru were here' would probably send a message to him on a subconscious level, for example. This can go both ways as well-If Suguru really, really wants or needs someone to know what he's feeling, he's going to send it to them, either on purpose or just subconsciously.
Loaning Power
At the same time the most simple and most important of the effects. This is the ability to turn support into literal power. It comes in two varieties. Literally transforming the support of a friend into physical power; such as cheering for Suguru to win will actually make him stronger. The degree of strength gained is relative to the amount of support given. Suguru is very sensitive to this particular effect, and just having a crowd cheering for him makes him stronger. The second variety is loaning the friend a skill or power in the literal sense. For example, Suguru was capable of using the techniques of Ramenman when he cheered him on in a fight, and Suguru loaned Warsman the use of his unique ability, the Burning Inner Strength. Later on, one character uses techniques from his entire 5 man team. It doesn't necessarily have to have anything to do with combat, just needing to be able to do something a friend can do. Think of it like cutting out the stage where a friend has to physically do it-the conviction of 'I want to help them do this' is enough.
Suguru might loan your character would be his Burning Inner Strength (火事場のクソ力, Kajiba no Kuso Djikara), called K.K.D sometimes. K.K.D is essentially the power of miracles; to surpass ones limits beyond all logic, to never surrender under any circumstances, the power to instinctively perform without thought, know things through intuition without knowledge and, most importantly, the power to take the smallest, one in a million chance and transform it into a certainty. Suguru's K.K.D is actually quite weak at the moment, only able to last a few seconds, but as canon moves on it becomes a far more formidable force.
He might also loan his fighting knowledge, essentially letting a character know how to wrestle like a professional. Or, he might just loan them his fantastic strength and endurance-Suguru can easily use building's as clubs, and military grade weaponry is just annoying to him.
Moving With Friendship Alone
A pretty simple power. Without thought or awareness, those affected by the friendship power will move their bodies automatically for the sake of their friend. Examples have come in the form of the brain dead Ramenman moving to grab Kinnikuman's hand and the similarly soulless Terryman leaping into action to protect Suguru. A different type of this ability was Terryman and Suguru moving in perfect unity when fighting side by side, and being able to create a tag team move with Neptuneman on their first try.
Miracles
The most open ended of all the effects. These are basically things which occur due to friendship which ignore all the laws of physics and pretty much tells logic to go screw itself. Created by a feeling of 'impossible doesn't matter when it comes to my friends', this can more or less do anything. Some examples include: Terryman's arms have been torn off, and so he calls out to a dead and headless Buffaloman in another dimension, who sends Terryman his arms. He does this twice, in rapid succession. The mask of the dead Warsman opens its mouth and spits out Warsman's signature weapon cut a wire cage to save Ramenman. The spirits of the dead or injured are able to literally lift Suguru up when he falls down, and help others to lift up great weights. The dead Ramenman is returned to life by the tears of spectators and his friends. One character's body is reduced to ashes, but can use Friendship Power to control the ashes to protect others. Naturally, this ability only occurs in desperate situations and requires complete and total dedication to the friend. I tend to think that it can't do things beyond the power of those sending the miracle, but it can defy the logic of how that power is used. For example, if a character that uses a gun sends a miracle, it might appear in the form of a bullet flying out of nowhere. But it couldn't appear in the form of a tank shell or a rain of bullets.
Friendship power canonically doesn't work all the time, and basically works whenever the story needs it to. So, it's not going to screw up any canon shenanigans. Right, so, if you think your character is close enough to Suguru to receive or give any of these effects, or you just have questions (I know it makes no sense, but it's Kinnikuman), please let me know. It's a pretty loose deal, so if you're not sure, just ask.
