Mecha-Cobra 3, A.K.A. Version 3 (メカコブラ3 Mekakobura 3 / バージョン3 Bājon 3)is a robot cobra created by Keen Lebron. He is Mecha-Cobra and Lazer Znake's brother. His default form is called "Version 3". He is not used as often as Mecha-Cobra, but is still used.
Version 3 (Form)Edit
The Version 3 form looks like a dinosaur with no legs and shoulders way up, with an upper jaw and a lower jaw, and a crest.
MC3 is yellow, orange and red.
Keen, after constructing MC2, later thought about making a super Mecha-Cobra (Primid Cobra), that required three times the power of Mecha-Cobra, so he went on and built MC3. Keen updated MC and MC2 to have the newest version and be capable of merging.
MC3 has the same roars and versions as Mecha-Cobra, except the M.I.C.P.O.E. version. 300px|center|The same with Mecha-Cobra, except for M.I.C.P.O.E. version.
