I got the amazing opportunity to create the Corebot characters for ReCore starting back in late 2014. Here is "Mack" as most people know him. He really is the Mack Core in the K-9 frame using the Yellow BareBones part set. There are a ton of variations you can get with these characters due to different cores, frames, parts, and colors so I am going to try to post only one per part set.
