I could give you a long list, but here is just a few.
Defeated John Stewart GL in seconds.
Stomped Metallo
defeated Nebrious ( who Zatanna stated was way beyond her power)
these feats were all before his first upgrade and he's had several.
After his last upgrade he was shown to be a physical match for Etrigan in Reign in hell. Etrigan who has belted Superman from earth to the moon with a single punch ad gas fought Lobo.
Now eliminating BD's strength (equal to Namor if not above after becoming full demon blood- royalty at that), Durability ( better than Namor), speed (at least equal), agility (far better). We then have his healing factor (in early issues I remember his torso reforming in seconds after a tank blast hit it) and the many varied powers of his trident.
powers that include
hell fire control.
time manipulation
dimensional travel
to name a few
