This could lead to a strange kind of respect and understanding, and perhaps even a form of friendship. They might start to hold back in their battles, not wanting to seriously harm the other.
Imagine a scene where Cliffjumper tries to appeal to Scorponok's sense of honor. Cliffjumper might say something like 'We're both warriors, we should fight with dignity.' Scorponok could respond with a scoff but also be a bit intrigued. This interaction could be a turning point in their relationship as they start to see each other not just as enemies but as worthy opponents.

This could lead to a change in their relationship and potentially even an alliance of sorts.
