5) Superboy (Jon Kent)
The most recent creation on this list, Jon Kent is only two years old – well, in real-world terms. First appearing in the Convergence arc, Jon is the ten year old son of the pre-Flashpoint versions of Lois Lane and Clark Kent. When those characters merged with the New 52 incarnations to become the only Lois and Clark, Jon remained the same and looks to be here to stay.
Since the advent of DC Rebirth, Jon has made quite the impact. Now operating as Superboy, the young Kent is being mentored in the ways of Superman by his dad and has formed an uneasy partnership with Damian Wayne‘s Robin (more on him in a moment). He’s been kidnapped by Mr. Mxyzptlk, brainwashed by Manchester Black and survived General Zod’s wrath, but through it all he’s demonstrated his father’s immense courage and his mother’s fierce spirit.
Despite his arrival marking a massive shift in Superman’s status quo, Jon has gone down incredibly well with fans since his debut. Let’s hope that the adventures of Superman and Son keep unfolding for a long time yet (and don’t fall victim to another pesky continuity wipe).
