Writer James Robinson will be joined by the artist for the two-part storyline in issues #7-8 of DC Comics second wave New 52 title.
"I've been reading this book as a fan since issue #1 and feel so honoured to be able to be part (in some way) of the restructuring of the new Earth 2," Cinar told The Source.
"Besides that, this is going to be my first collaboration with James Robinson, so needless to say... there are good times ahead!"
A preview of the artist's cover for Earth 2 #8 shows the world's last Amazon standing with villainous New God Steppenwolf.
Cinar replaces ongoing artist Nicola Scott, who was previously solicited for issue #7. It is unclear whether or not she will return after his issues.
The artist was formerly working on The Fury of Firestorm, with Dan Jurgens replacing him and Joe Harris as both penciller and writer on the title.
The news comes as part of the most recent artistic shakeup of DC's line, with Alberto Ponticelli replacing Mateus Santoluocco as ongoing artist for Dial H and Ivan Reis and Joe Prado taking over from Jim Lee Justice League while Ardian Syaf steps into the pair's shoes on Aquaman.
