I believe that colossus is a “beyond god tier champ”
I don’t know how people will receive this post, but this is my personal opinion. Colossus was recently buffed (around 6 or 7 months back) and he’s now an amazing champ. His sustainability alone makes him amazing, adding to that his many important immunities. His triple immunities to bleed, incinerate, and coldsnap/frostbite makes him a great contender for nodes like trial by fire, biohazard, and iceman. His ability to gain +100% power in situations where his AA is lowered makes him great for matchups like domino. His immunity to armor break effects (unless inflicted by a tech champ) and his ability to go past 40 armors grants him immense attack and even more sustainability (he can also auto fight his way through ROL WS). His specials hit like a truck, and his sp3 further grants him even more sustainability through lowering attack and crit rating. His fury off the heavies are insane, and gets even more amped up by the armors. He may need synergies like OR (but lots of champs like ghost rely on synergies) and OR is a great champ anyways. He takes around 40 damage a parry with many armors even in places like act 6 with extremely stacked health pools. Some people say that he is hampered by stun immune nodes, but I think this is false. He does lose some damage from them, but even without he hits like a truck. KT recently did a lab clear with him where he was hitting 50k+ specials (assassins bypasses the damage cap) with absolutely no fury from the heavy active. I think he has a lot of “beyond god tier” characteristics. He has the sustainability, the damage, and the immunities to tackle and destroy a lot of endgame content. He’s generally ranked with champs like iceman, Emma, sunspot, and havok. I think he’s a step above these champs and that he deserves a little more recognition.
