Check it out guys. I did a 10094 Damage Combo with X and Dante.
Its impracticable since it requires 5 meter and Full Power Infinity Storm. Basically you have Dante go DT then switch to X and gain 4 Meter as X. Not worth it.
But I'm posting it here and it only for the world record as currently there is no Tier 2 HP (Ryu/Iron Man etc) 100% combo on the internet. I tried to abuse the early damage scaling and put in the most meatiest of hits before juggle rate fall off to achieve this.
The same combo done on no DT Dante does 9955 damage. There is a possibility I can still put in some more umph and make it reach 10000 with 4 Meter and Power Infinity Storm.
