For those of you who do not know of Franco-Belgian comics aside from Tintin or Asterix (Like, seriously, please do yourself a favour and read Percevan, Spirou or Marsupilami! ;w; They're SO good!) this character is VERY obscure.
He's called Catmeleon and is from a comic Called Timmy Titan. An interesting concept but I only know of one album that was ever released! Aside from being able to shapeshift he also has eye lasers that temporary inflate those struck by it.
A strange character indeed!
