Kolivan

My favourite nonsensical ship in Voltron is Allurivan, Allura X Kolivan because Kolivan treated her better than Lotor and Lance combined, he bows when he meets her, doesn't criticise her for hating galra and actually earns her trust by taking out Zarkon's ship and protecting her in the Komar and make sure she escapes safely. He also compliments her in later episodes.

if kolivan had access to communicate the blades they could be able to be transported to the place kolivan was if they told keith using the red lion and saved him thus transporting him to the atlas/ castle of lions to let him heal up
