I was bored, and I've never seen sprites of these, so I did some sprites of Tien doing Kamehameha.  I think it turned out pretty well, so I decided to post it here.

For the charging pose, I took Goku and swapped his head with Krillin's.  For the shooting pose, I just put Goku's hands on the Blast Cannon pose.

Give credit if used!

I've seen Tien Kamahama sprites. But these still look good.
