Fuse two champions ultimates and create the most epic champion possible
 

I'll start this...
Jarveon - Grand Cataclysm: Global jump with earth shattering fall anyone?

Edit: Bonus points if not using Karthus or Darius. Negative points if Karthus+Darius...

Veigthus
Primordial Requiem
WHERE IS YOUR GOD NOW?

Karthraka

Jk

Mordevelynn
ALWAYS SHIELD NEVER DIE

Karthraka. Press R.

Dear lord....... 1 shotting AP/AD carry at level 11....

Malpharius.... AOE true damage execution knock up that resets on kills.

Kog'maw + Anivia
Acid Frost.
works like anivias ult but lowers magic/armor res to people in it (using kog's q power) and kog'maw ult is faling frm the area hitting enemys inside. (like gankplank's only faster and more accurate shots) does 150% more dmg to champions. (does slow and add frost to target)

Corius
Missile Guillotine-7 darius ults that refresh on kill. Big one guillotine does 100% of someones hp

Master Olaf
Highrock Immune to slows, stuns, gain ms and as, refresh on kill, ar pen, dmg resistance

Ashe and Draven.

Simple.

Shenaka: Teleport to EVERYONE.
