What's the theme of Next Fusion champ?
Can I propose a few?
1)Saint George or Demetrius. Magic Affinity attacker or mass healer support. "Lay on hands" or "Cross Divination" therapeutic in such case and creates team shield for 1 round every six turns.
2)Knight Templar. Legendary Version of Sacred faction Rare quality Templar. Spirit affinity, with skillset variation to include all team, still a Defender, similar aura. Similar looks, white cloth, you can paint the leather bits red and the black ones blue. I don't like the helmet much, give him something like Errol's or just remove the silly horns and ball from it. Crusader's helmet from the same faction - who is uncommon - looks better. 3-5% Turn meter bonus passive.
3)Hammer and Sickle. Bear skinwalker. Force affinity attacker. Immune to Freeze and Stun. Vulnerability to poison.
4)Uproar Goldmane. Lion/Rakhsasa looking, Golden colors, Skinwalker Attacker, Void Affinity. A1: "Safari Hunting" Attacks an enemy 5 times. Leaves them "scarred and panicked" a special that combines stun and gradual HP loss. A2: "King of the Jungle". Attacks all enemies twice. % to provoke them to attack anyone else from his team but him. Passive: "Leak Wounds". 30 % to heal up to 25% of his max HP each turn. Ability: "Cornered". Attacks twice as hard when 40% or less HP left.
BTW, inspiration for possible upcoming factions(in addition to angels and ancient greek mythology one and whichever ones I and others already proposed):
