Hound

 '' "I'm a wicked Warrior robot." -  ''Hound  Hound is an Autobot warrior who is as powerful as he is loyal, a Badass Commando who would fight to the bitter end on the battlefield whilst protecting his comrades, A cheerful and respected Autobot who's wide arsenal of weaponry and skill in combat make him a force to be reckoned with and Optimus highly recognizes this. Hound became one of the last remaining Autobots on Earth, after four years of hiding from Cemetery Wind, Hound joined his leader in their mission to avenge their fallen comrades including Ratchet and Leadfoot.

Personality and Characteristics
"That's a bad idea, but I'm all about bad ideas."

Hound is a loyal, courageous and generally likeable Autobot, he is supportive to those that he cares about and will do whatever he can to protect them. Although he has been shown to become irritated by several things e.g. he became slightly annoyed by Drift's high term of vocabulary which he found rather confusing to the point were he threatened him with a grenade, (though this might have been on a sarcastic note.)

He appears as sturdy and serious in most situations however this does not prevent him from making a badass pun whilst in battle. In addition he meets the mission's priorities and does a good job of keeping those in their place as demonstrated by holding Crosshairs at gunpoint onboard Lockdown's ship for the latter not wanting to help the Autobot's locate Optimus Prime and Tessa Yeager where Hound firmly stated they were there to rescue them (even threatening to kill him if the latter did not comply.)

Strength and Skills
Hound is one of the toughest Autobot's on Earth, he is extremely skilled in combat and weaponry as he was able to hold off against numerous waves of manufactured KSI drones for a prolonged period of time, despite eventually running out of ammo he was able to utilize various tactics by using his helmet, belt and even his cigar to defeat them all; although by the end of the battle Hound was exhausted. He has a huge arsenal of weaponry including a number of selective hand guns, pistols and especially his Gatling gun.

Optimus Prime
"HE'S ALIVE" - Hound upon hearing his leader's voice.

Optimus and Hound have a good friendship, as Hound greatly respects Optimus' leadership and stands with him on his decisions, Optimus in turn views Hound as brave and powerful Autobot as well as a loyal friend; when the two reunited after four years Hound was overjoyed to see his leader, with him happily shooting at the sky upon his return. It is implied that Optimus views as Hound as the most responsible out of the others, although Hound stated that Optimus' past vow to never kill human's was a mistake, however once Optimus declared that would kill the human responsible for the death's of the Autobot's, Hound was pleased.

After Optimus had been captured by Lockdown, Hound supposedly took command of the Autobot's in his absence, and was more than willing to rescue his leader. Their friendship was further established as Hound was the very first Autobot that Optimus called out for when he was imprisoned on board Lockdown's ship. hound was relieved to find him alive and quickly came to his aid by piloting a detachable ship onboard the bounty hunter's vessel, Optimus was mostly grateful for hound and the other Autobots for saving him, this act strengthened their bond together.

After being separated by a blast shot, Hound boldly fought against the powerful enemy waves of KSI drones until he eventually used up all his energy and could not continue to battle, to his relief Optimus arrived in time to help his friend with the aiding of the Dinobots, Hound was very grateful to his leader and Optimus was mostly likely proud of what Hound had done to protect the Yeager family and the Seed altogether. Both Optimus and Hound are extremely loyal towards each other acting almost like brothers.

Crosshairs
"What's in it for you is I don't kill ya ." - Hound firmly addressing Crosshairs Of all the Autobots Hound has shown to be mostly irritated by Crosshairs attitude as shown when the latter enjoyed viewing the others fighting and expressed his desire of becoming the new leader where Hound simply shook his head. During the Autobots infiltration on Lockdown's ship Crosshairs was all ready to leave after barely searching it was immediately after when he brushed Cade aside asking what was in for (him) Hound replied by pointed his gun and firmly informed him that he would kill him if he was uncooperative to which Crosshairs complied labeling his methods as very persuasive.
