Hi, i'm new to posting here. But I've been watching some topics here including this one!

This is looking great! I'm excited for this new update whenever it's released.

I have a few ideas or concepts that you could use. (I've been thinking about them for awhile, but decided now to post it.)

You could have:

Neutral Special: being fireball jutsu (and have fire flower jutsu happen 1/8 of the time) and have him able to angle the fireball shot. but first inhale before the release of the jutsu so you can angle it after. You can base the animation off of Ice Climbers' Blizzard.

Side Special: Snake Sword Charge. He basically performs Ike's Quick Draw but with lightning effects. and different sword positioning. He puts his sword back in it's sheath. (Enters helpless frame if used in the air after sheathing his sword)

Up Special: A Hi-Speed jump or teleportation.

Down Special: Chirodi. (Ground only) you know the concept. Work's like C.Falcon's Raptor Boost but you can't fall off the ledge. He can charge his hand. (Same duration as you have now is good)

Down Smash: Chirodi Nagashi. you know the concept of this too. but have quite an okay delay after the use. The effect can range like nyaru's love. but one hit.

These are just ideas i had.
