In my headcannon, Optimus Prime be partner to Twylight. They fit. Leaders. And clever. In one example, Twylight worries Optimus might punish her family if he knew of her sin; the Marer Do Well and Walking Dead hoaxes, the cheerleading and swamp puppetries, the gambit to steal Novo’s pearl and hurting the CMC and Flurry. But Optimus is more forgiving.
Also in my headcannon, Optimus Primal be partner to Sunny Starscout. They fit. And Optimus Primal gains the Maytrix of Leadership contains Primus’s essence and becomes Primal Prime; similar to Optimal Optimus and inheriting the Star Sabre and Optimus Pri.he’s axe. And on time to defeat Galvartronus Prime, the form of BW Megartron similar to the Transmetal 2 dragon one cause by the Maytrix of Chaos containing Unicron’s essence.

Optimus Primal be the very Maximal I want the MLP ones of Gen 4 and 5 to meet the most. The noble leader. And his gorilla form helping to enhance the heartwarming scenes; the ‘monster’ who’s a gentle giant.
