Second-in-command

The second-in-command refers to a Transformer whose status is, well, second to the commander's. A Transformer who is second-in-command is not necessarily ranked Sub-Commander, while a Transformer ranked Sub-Commander is usually the second-in-command. The rank generally varies between factions. For the Autobots and the Maximals, the rank is usually overlooked, but it still receives its own holiday. For the Decepticons, choosing a Second-in-Command is a very tough decision. Pick one too loyal, and everyone will ignore him. Pick one too bold, and the leader may find himself scrapped.
