Wildmutt & Upgrade.
I always feel that when Wildmutt salivating looks like very Q!
Allow me to explain those roles of data:
Upgrade's body composition may be close to mercury,
It can invades any metal, and then upgraded to a high-tech products;
Wildmutt holds keen animal instinct,
Although it's visionless, still can use ear-cracks catching other's cretonne, even though the heat source.
As the result, they're should playing "Chase You" game in this pic... Should be.
After all, Upgrade can only invades into the metals, not the stupid dog.
