- This is the strongest "Earthbound Immortal" in the game, in terms of combined ATK and DEF (in addition to DEF alone). This card is also tied with "Earthbound Immortal Ccapac Apu" for the highest ATK of the "Earthbound Immortals".
- It also has the highest DEF of all Insect-Type monsters, tied with "Perfectly Ultimate Great Moth".
- Uru (or Uro) are people who live in man-made totora islets in Lake Titicaca, which is said to be the origin of the Inca Empire.
- Uru is also a Quechuan word meaning "spider".
- This monster's ability to take control of opponent's monsters is also similar to that of Roman Goodwin, the owner of "Uru", who uses spiders to brainwash his victims.
- In addition, this "Earthbound Immortal" could represent Roman as being the "boss" of the Dark Signers and his mark as being the Old Ener-D reactor itself while the other Dark Signer marks (except the whale and condor) are the control units that the Ener-D reactor relies on.
