SHOCKWAVE
Sub-group: Mini-con
Affiliation: Decepticon

Cartoon appearances: none
Comics appearances: none

Other Appearances:  Being a mini-con, it's safe to assume this is a different individual with the same name as other characters.  The original Shockwave debuted in 1985.  The next came in 1990 in Action Master form.  There were several other form/characters named Shockblast, a primary character of TF: Energon and the Alternator.

TANKOR
Sub-group: Mini-con
Affiliation: Autobot

Cartoon appearances: none
Comics appearances: none

Other Appearances:  Again, as a Mini-con, I assume this is a different individual with the same name as other characters.  The first Tankor toy was released as part of the 2000 Beast Machines line, a vehicon General, see also Tank Drones released in 2001.
