Support Champ idea
He is an old soul trapped inside a body suit armor ,,he has no flesh no blood,,but he control his armor,his abilities is to use his armor to protect allies and also attack enemies , he can merge with allies to make a powerful soldier with high status but this ability drains all his power for a short time but in return he create a powerful Allie for a short period of time ,, it is a cool champ and you already got the technology to merge champs(yumi) the difference is only visual and this champ has no hp and cannot buy potions as i said he has no flesh no blood so he only has his armor once his armor is down he is dead and to kill him is to destroy his armor we can make him like zac passive you destroy each piece of armor to kill him (what if he has 1 armor plate left?) well he is a merger so all his abilities is to support allies and put his armor on them so the only way to take his armor down is buy taking the one whom ıs merged with . a cool warrior champ .
