Angel
Sorry to squelch your superhero dreams, but you will not morph into "Angel Man" upon your death. As appealing as it might seem to us, humans do not become angels when they die.

God specifically created angels to be his assistants. Their job description includes: worshiping God; relaying messages to people; protecting people; administering encouragement, guidance and punishment to people (on an as-needed basis); and fighting the true forces of evil.

Angels are not worthy of worship. They are created servants of God. Satan, along with legions of evil angels (demons) who followed him in his rebellion against the Lord, were evicted from heaven. Far from the benign, shoulder-perching devils of cartoons, demons are truly evil. Their intent is to keep us from God and drag us into hell with them. Fortunately, God has more power than Satan and his minions. God and his angels are on our side. While the true forces of evil will suffer throughout eternity in the lake of fire, angels will fulfill their ultimate purpose of offering continuous praise to God.

Angels are spirit beings, distinctly different from humans. They work on behalf of God's people.
