Some fans don't know, but the Blue Beetle is not a sole hero, in fact, there have been three Blue Beetles in DC Comics history.
One that had very strong connections was Ted Kord. In many ways, Ted Kord is just like Batman, as he is a wealthy genius who uses gadgets to save the world, and does not have superpowers. It is because of this that Batman and Ted are great friends in many continuities. They have a mutual respect for their technical prowess and ability to overcome all odds.
Sadly though, Ted Kord would give his life to save the world, and it's because of this that Batman looks after the newest Blue Beetle.
