The second (and sadly, final) arc of Robo Machines dealt with the escalation of the conflict of the war, introducing first Zod and then Casmodon as threats. There are some big changes across this one - the Security Forces' leader, Ex-El, disappears without warning before the start, Stron-Domez quickly changes, new Security Forces characters appearing out of nowhere... There's also a very unusual ending - Tully obviously had more planned.

I can only speculate as to why the strip ended - it could have been unpopular, or it could have been that Challenge of the Gobots was beginning to filter over to the UK, and Bandai wanted the conflicting continuity of the comic ended - by Autumn, World Distributors had issued an annual containing stories following the cartoon continuity. Another reason to dislike the show...

The second arc was ran in colour - well, technically. The black and white was joined by red, and the results weren't particularly impressive - these scans have been converted to black and white so they look a bit better.
