Copied and pasted from an old thread where parrperson asked about Lion:
Lion is one of the most underrated characters. He is very, very good. Some basic stuff…
You can use 44K to punish whiffs, either out of backdash or after you evade something. 44K,P+K, KK is guaranteed on most characters and does a lot of damage. A common setup is 6P (blocked), and do 44…K to do 44K out of backdash to punish their elbow.
What sets him apart are his evasive property moves, especially FC 6P. There is a reason this move is throw counterable. It naturally evades low P at frame disadvantage. It can also evade most elbows in the correct foot position. A common setup is low P (blocked), FC 6p. If you pay attention to stance, you can make the opponent keep blocking after your low p is blocked, and then start mixing it up with k~g throw, 2k+g, or backdash -> evade, etc. You can get pretty creative once they freeze up.
His command evade 9/3p+k+g also evades a lot of things (at disadvantage), but you have to know what foot postion is required for specific moves, so a lot fo training mode experimentation is required for having a strong Lion.
On top of all that stuff, he has a lot of great low pokes, his 3k+g/2k+g or 6k+g mixup after techroll is good, 214P sabakis everything but elbows.
